This October 2006 paper is a study of the ignition of non-fire-resistant hydraulic fluid sprays, conducted by the National Institute for Occupational Safety and Health. Hydraulic fluids are widely utilized in many industries, such as mining and construction, for power transmission. Most hydraulic fluids are combustible and are used under high pressure to transmit power or motion. Both an open flame and a hot steel surface were used as the external heat sources. With the open flame as the heat source, the minimum oil temperature and minimum spray nozzle pressure that resulted in an ignition were measured.
